the take

Near-Opus agentic muscle at half the Opus price, and the one I would hand most day-jobs. Off the board only because it is days old and reports vendor evals, not the standard suite. Watch this one.

Not ranked: Anthropic doesn't publish enough comparable public benchmarks to place it fairly. How ranking works.
